	'''Unit of Measure (UoM)'' refers to the unit in which an environmental indicator or quantitative measure is expressed. It defines the scale and type of the result value, such as kilograms of CO₂-equivalent or megajoules of energy.		'''Unit of Measure (UoM)'' refers to the unit in which an environmental indicator or quantitative measure is expressed. It defines the scale and type of the result value, such as kilograms of CO₂-equivalent or megajoules of energy.

	The Unit of Measure indicates the unit of measurement for the value being reported, independently of what it is reported per (e.g., per kilogram or per ~~functional unit~~). It answers the question: “What is the quantity expressed in?”. The per unit is the Unit of Declaration (UoD). Examples price UoM is $, and the the UoD can be per kg, per piece or per ~~supply chain unit~~ ([[https://imde.io/index.php?title=Supply_Chain_Unit_-_TX\|SCU]])		The Unit of Measure indicates the unit of measurement for the value being reported, independently of what it is reported per (e.g., per kilogram or per piece).
